Engineering Selection Recommendations

Active Status Priority: Parts with Active product status are preferred for new designs and long-term availability. The TE Connectivity 5-146254-3, 5-146256-3, 5-146257-3, 5-146261-3, Würth Elektronik 61300621121, and all Samtec HTSW variants are currently active. Obsolete parts (104350-3, 146256-3) should be used only when existing inventory must be maintained or when legacy design compatibility is required.

RoHS Compliance Consideration: If RoHS3 compliance is required, select from: 5-146254-3, 61300621121, HTSW-103-07-F-D, HTSW-103-07-L-D, or HTSW-103-07-S-D. The original 90824-406H is RoHS non-compliant. For applications where RoHS compliance is mandatory, 5-146254-3 offers the highest inventory availability (18156 units) with tin contact finish matching the original part's mating surface.

Contact Finish Selection: Tin-finished contacts (90824-406H, 5-146254-3) provide cost-effective solutions for standard applications. Gold-finished contacts (5-146256-3, 5-146257-3, 5-146261-3, Samtec HTSW series, 61300621121) offer enhanced corrosion resistance and are suitable for harsh environments or applications requiring extended shelf life.

Temperature Range Consideration: The Samtec HTSW series extends the upper operating temperature to 125°C, compared to 105°C for TE Connectivity and Würth Elektronik alternatives. Select HTSW variants for applications requiring this extended thermal capability.

Inventory Availability: TE Connectivity 5-146254-3 maintains the largest inventory (18156 units), followed by 5-146257-3 (13942 units) and 5-146261-3 (6719 units). These three parts represent the most readily available substitutes.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 90824-406H with any of the listed parts without PCB redesign?

A: Yes. All listed substitute parts maintain the critical mechanical parameters: 0.100" (2.54mm) pitch, 6 positions in 2 rows, 0.100" row spacing, through-hole mounting, and push-pull fastening. PCB footprints are compatible. Minor variations in contact length and insulation height fall within acceptable tolerances for standard through-hole applications.

Q: What is the difference between tin and gold contact finishes?

A: Tin-finished contacts (90824-406H, 5-146254-3) are suitable for standard indoor applications with typical shelf life expectations. Gold-finished contacts provide superior corrosion resistance, extended shelf life, and better performance in humid or corrosive environments. Gold finish does not affect electrical performance in standard applications but increases component cost.

Q: Are the TE Connectivity AMPMODU Mod II parts truly obsolete?

A: Parts 104350-3 and 146256-3 carry Obsolete product status, indicating they are no longer manufactured. However, inventory remains available from distributors. These parts are functionally equivalent to active alternatives and may be used if existing stock is accessible. For new designs, active parts are recommended.

Q: Does the Samtec HTSW series require different PCB footprints?

A: No. The HTSW series maintains the same 0.100" (2.54mm) pitch and 2-row configuration. Footprints are directly compatible. The HTSW series offers extended operating temperature range (-55°C to 125°C) and RoHS3 compliance as primary differentiators.

Q: What is the significance of the contact material difference between Phosphor Bronze and Copper Alloy?

A: Both materials are acceptable for this connector category. Phosphor Bronze (used in 90824-406H and Samtec HTSW series) provides consistent spring characteristics and durability. Copper Alloy (used in TE Connectivity and Würth Elektronik parts) offers similar performance with slightly different mechanical properties. Selection does not affect electrical compatibility.

Q: Which substitute offers the best RoHS compliance and availability combination?

A: TE Connectivity 5-146254-3 combines ROHS3 compliance with the highest inventory availability (18156 units) and tin contact finish matching the original part. This part is the most direct replacement for the 90824-406H when RoHS compliance is required.

Q: Can I mix and match contact finishes in the same connector assembly?

A: No. All mating contacts within a single connector assembly should use the same finish specification. Mixing finishes may result in inconsistent contact resistance and reliability. Select a single part number for complete assemblies.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity and requires no special storage or handling precautions. All listed parts carry MSL 1 rating, confirming compatibility in standard warehouse and manufacturing environments.
