02 / VERIFICATION STANDARDS
Four Engineering Verification Standards for Alternative Sourcing
Cross-referencing connectors requires verifiable electrical and mechanical tolerance data rather than visual estimation:
Pin Pitch & Footprint Tolerance
Center-to-center pitches (1.27, 2.0, 2.5, 2.54, 3.0, 3.5, 4.0, 5.0 mm) are matched within ±0.05mm tolerance. Verify PCB solder pads against 2D dimensioned PDF drawings and 3D STEP models without redesigning the PCB.
Contact Normal Force & Deflection
Contact fingers use high-elasticity beryllium copper or phosphor bronze with gold-over-nickel plating (1u" to 30u"). Working deflection is calibrated between 0.8mm and 2.2mm, delivering stable 0.8N–1.8N contact force across >5,000 to 10,000 cycles.
Current Carrying & Thermal Limits
Continuous ratings range from 1.5A to 7.0A per contact on battery fingers and up to 30A–40A on power blades. Laboratory testing confirms thermal elevation remains under 30K at rated continuous DC current under ambient 25°C.
Insulator Material & Reflow Endurance
Insulator housings are molded from high-temperature liquid crystal polymer (LCP) or PA9T with UL94 V-0 flame-retardant rating. Parts withstand lead-free reflow peak temperatures up to 260°C for 10 seconds without blistering or warping.
03 / REVIEW CHECKLIST
Before requesting an alternative battery connector
What is the sourcing goal?
Availability · second source · revised design
View review points
Tell us whether the original part is discontinued or difficult to source, you need a second source, or you are selecting a connector for a revised design. Include your expected quantity and target date. Available models, pricing and lead times require separate confirmation.
What must remain unchanged?
Existing mating part · PCB · mounting
View review points
State whether the existing mating part, PCB and mounting position must be retained, or whether both connector halves and their mounting arrangement may change. Distinguish replacing one side from selecting a new pair. Mark unknown items as “to be confirmed”.
How should a preliminary candidate be used?
Individual comparison · drawing · documentation
View review points
Record differences in pinout, contact positions and mounting dimensions for each candidate. Check samples against the project requirements before choosing the purchasing part number.
Use the existing selection-information checklist to organise available information, then contact us using the details on this page.
Confirm against the specific model documentation
Check the part number, drawing revision, pinout and mounting dimensions.
From original information to candidate review
- 01
Identify the original and your goal
Share the original reference, drawing and application, and explain the sourcing goal.
- 02
List fixed constraints
Distinguish one-side replacement from a new selection, and review dimensions, mating side and mounting.
- 03
Compare candidates and confirm documentation
Preliminary candidates are for comparison; confirm the specific model and documentation before discussing purchasing.
04 / FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions about Connector Cross References
Can Kangsheng provide pin-to-pin replacements for discontinued Molex or TE battery connectors?
Yes. When pitch, pin count, and PCB pads match, Kangsheng supplies drop-in replacements. Share your original part number or PCB footprint drawing to confirm dimensions and sample availability.
What engineering information is required to find an alternative battery connector?
Provide the original manufacturer part number, pin count, center pitch, working height, maximum continuous current, and whether the mating battery interface must remain unchanged.
How do you verify whether an alternative connector can handle the same current?
We verify contact cross-sections, spring materials, and plating thickness against your current profile, and confirm thermal rise stays under 30K at rated continuous DC current.
Can Kangsheng modify housing height or pin layout if an exact off-the-shelf match is unavailable?
Yes. Kangsheng operates in-house tooling workshops. We can adjust terminal bending heights, pin counts, or mold inserts to match custom PCB constraints with low NRE and fast turnaround.
What is the typical lead time for cross-reference sample evaluation?
Standard catalog cross-reference samples ship within 24 to 48 hours along with 2D drawings and STEP models. Custom-modified tooling samples typically require 7 to 14 days.
