Engineering Selection Recommendations

For direct replacement with minimal design impact: The 61232620621 from Würth Elektronik is the primary equivalent. It maintains identical electrical and mechanical specifications with the original 61202620621, differing only in packaging format and active product status. This part is recommended for applications requiring no design modification.

For applications with extended temperature requirements: The Samtec HTST-113 series (HTST-113-01-L-DV, HTST-113-01-L-DV-A, HTST-113-01-S-DV, HTST-113-01-L-DV-P-TR, HTST-113-01-TM-DV-P-TR) extends the lower operating temperature to -55°C compared to the original -40°C minimum. These parts use Phosphor Bronze contacts with LCP insulation, providing enhanced mechanical properties. The gold-plated variants (HTST-113-01-L-DV, HTST-113-01-L-DV-A, HTST-113-01-L-DV-P-TR) maintain contact finish compatibility with the original design.

For applications with standard temperature range and tin finish: The HTST-113-01-T-DV and HTST-113-01-T-DV-P-TR variants operate to -55°C ~ 105°C with tin-plated contacts, suitable for cost-optimized designs where the reduced upper temperature limit is acceptable.

For high-volume automated assembly: Parts with "Pick and Place" features (61232620621, HTST-113-01-L-DV-P-TR, HTST-113-01-T-DV-P-TR, HTST-113-01-TM-DV-P-TR, N2526-6V0C-RB-WE) are optimized for automated placement equipment.

For applications with current rating constraints: The N2526-6V0C-RB-WE from 3M provides mechanical compatibility but with a reduced current rating of 1.75A per contact compared to 3A or 3.4A in other alternatives. This part is suitable only for applications where current requirements do not exceed 1.75A per contact.

All substitute parts maintain UL94 V-0 flammability compliance and RoHS3 compliance status, ensuring regulatory equivalence for the original design.

Frequently Asked Questions (FAQ)

Q: Can the 61232620621 be used as a direct drop-in replacement for the 61202620621?

A: Yes. The 61232620621 maintains identical connector geometry, electrical ratings, and mechanical specifications. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tube) and active product status. No design changes are required.

Q: What are the key differences between Würth Elektronik and Samtec alternatives?

A: Würth Elektronik 61232620621 uses Copper Alloy contacts with Polyamide insulation and operates -40°C ~ 125°C. Samtec HTST-113 series uses Phosphor Bronze contacts with LCP insulation and extends the lower temperature limit to -55°C. Both maintain identical 26-position, 2-row 0.100" pitch geometry and push-pull fastening.

Q: Are the Samtec HTST-113 variants with different contact finishes interchangeable?

A: The HTST-113 variants with gold-plated contacts (HTST-113-01-L-DV, HTST-113-01-L-DV-A, HTST-113-01-L-DV-P-TR) are interchangeable with the original gold-plated design. Tin-plated variants (HTST-113-01-T-DV, HTST-113-01-T-DV-P-TR, HTST-113-01-TM-DV-P-TR) provide cost reduction but require verification that tin finish is acceptable for the mating connector and application environment.

Q: What is the significance of the "Board Guide" feature in HTST-113-01-L-DV-A?

A: The Board Guide feature provides additional mechanical alignment during assembly. This variant is functionally equivalent to other HTST-113-01-L-DV options but offers enhanced positioning accuracy for automated placement processes.

Q: Why does the N2526-6V0C-RB-WE have a lower current rating?

A: The N2526-6V0C-RB-WE is rated at 1.75A per contact compared to 3A or 3.4A in other alternatives. This reflects differences in contact material (Copper Alloy), contact geometry, and insulation material (PCT Glass Filled). This part is suitable only for applications where current per contact does not exceed 1.75A.

Q: What packaging options are available for high-volume production?

A: Cut Tape (CT) and Tape & Reel (TR) packaging options are available for automated assembly: 61232620621 (Cut Tape & Digi-Reel), HTST-113-01-L-DV-P-TR (Cut Tape), HTST-113-01-T-DV-P-TR (Tape & Reel), HTST-113-01-TM-DV-P-TR (Cut Tape), and N2526-6V0C-RB-WE (Cut Tape).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance (61232620621, HTST-113 series) or RoHS compliance (N2526-6V0C-RB-WE), ensuring regulatory equivalence with the original 61202620621.

Q: What is the operating temperature range difference between variants?

A: The original 61202620621 and 61232620621 operate -40°C ~ 125°C. Most Samtec HTST-113 variants extend the lower limit to -55°C. The HTST-113-01-T-DV and HTST-113-01-T-DV-P-TR variants reduce the upper limit to 105°C. The N2526-6V0C-RB-WE operates -55°C ~ 105°C. Verify temperature requirements before selection.
