Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

Connector type (Header), contact type (Male Pin), and pitch (2.54mm)
Position count (8) and row configuration (2 rows)
Mounting method (Surface Mount) and shrouding style (Shrouded - 4 Wall)
Termination type (Solder) and fastening mechanism (Push-Pull)
Contact shape (Square) and material flammability rating (UL94 V-0)
RoHS3 compliance and electrical ratings (minimum 3A current, 250V voltage)

All identified substitute parts meet these core requirements. Variations in contact length, insulation material, contact finish, and operating temperature ranges are secondary parameters that do not preclude substitution when primary electrical and mechanical specifications align.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment.

Würth Elektronik 61230820621 provides the closest form-factor match within the same manufacturer family. This part transitions the original design to an active product line while maintaining the WR-BHD series designation. The insulation material upgrade from PA6T to PA9T and enhanced contact finish specifications support improved reliability. Operating temperature range reduces to -40°C ~ 105°C, which remains suitable for most industrial applications.

Samtec HTST series (HTST-104-01-L-DV, HTST-104-01-S-DV, HTST-104-01-S-DV-P, HTST-104-01-S-DV-P-TR, HTST-104-01-T-DV, HTST-104-01-TM-DV) offers expanded operating temperature capability to -55°C ~ 125°C with phosphor bronze contacts and liquid crystal polymer insulation. These parts feature higher current ratings (3.4A per contact) and are available in multiple packaging configurations (Tube, Tape & Reel, Bulk). The HTST-104-01-S-DV-P-TR variant provides tape & reel packaging optimized for automated assembly.

3M N2508-6V0C-RB-WD maintains copper alloy contacts and polycyclohexylenedimethylene terephthalate insulation material, offering the closest material composition to the original part. Current rating of 1.75A is lower than the original specification and may require circuit-level evaluation for applications demanding full 3A capacity.

Frequently Asked Questions (FAQ)

Q: Can I substitute the discontinued 61200820621 with the 61230820621?

A: Yes. Both parts share identical connector type, pitch, position count, row configuration, mounting method, shrouding, termination, and fastening specifications. The 61230820621 is the active successor within the Würth WR-BHD series and maintains full electrical and mechanical compatibility.

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

A: Würth parts (61200820621, 61230820621) use polyamide insulation and copper alloy contacts. Samtec HTST series uses liquid crystal polymer insulation and phosphor bronze contacts, offering superior thermal stability and higher current ratings (3.4A per contact vs. 3A). Samtec parts support extended operating temperature range to -55°C and are available in multiple packaging options.

Q: Is the 3M N2508-6V0C-RB-WD a direct replacement?

A: The 3M part meets all primary mechanical and electrical specifications but has a lower current rating (1.75A vs. 3A). Applications requiring the full 3A capacity must evaluate circuit requirements before substitution. Material composition (copper alloy and glass-filled PCT) closely matches the original design.

Q: Which substitute offers the best availability?

A: Samtec HTST-104-01-S-DV-P-TR (tape & reel packaging) and HTST-104-01-T-DV (bulk packaging) show the highest inventory levels (935 and 1019 units respectively) and are optimized for high-volume manufacturing. Würth 61230820621 provides 968 units with standard tube packaging.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant or RoHS Compliant certification, ensuring regulatory compliance for EU and equivalent markets.

Q: What packaging options are available for automated assembly?

A: Samtec HTST-104-01-S-DV-P and HTST-104-01-S-DV-P-TR include pick-and-place features. The HTST-104-01-S-DV-P-TR variant is supplied in tape & reel format, standard for automated surface mount assembly lines.

Q: Do operating temperature ranges affect substitution decisions?

A: The original part operates -40°C ~ 125°C. Würth 61230820621 reduces the upper limit to 105°C. Samtec HTST series extends the lower limit to -55°C while maintaining 125°C upper limit. Application temperature requirements must be evaluated against these ranges.
