Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select M22-2011646 as the primary substitute. This part maintains full compatibility with M22-2011605 designs, offering active product status and continued manufacturer support. The only difference is contact finish (Tin vs. Gold), which does not affect electrical performance for standard applications. This part is recommended for designs where form factor and mechanical compatibility are critical.

For Enhanced Performance Applications: Samtec TMM-116 series parts (TMM-116-01-F-S, TMM-116-06-G-S, TMM-116-06-L-S, TMM-116-06-S-S, TMM-116-06-T-S) provide superior current handling (3.2A per Contact vs. 1A) and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). These parts are suitable for applications requiring higher current capacity or operation at elevated temperatures. LCP insulation material offers improved thermal and chemical resistance compared to Nylon 6T.

For Board Stacking Applications: Samtec TW-16 series spacer connectors (TW-16-02-L-S-160-100, TW-16-07-G-S-160-355) are designed for multi-board stacking configurations with defined stack heights and tail lengths. Select based on specific stacking height and tail length requirements of the application.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can M22-2011646 be used as a direct replacement for M22-2011605? A: Yes. M22-2011646 is mechanically and electrically compatible with M22-2011605. Both parts share identical pitch (0.079" / 2.00mm), position count (16), contact material (Phosphor Bronze), operating temperature range (-55°C ~ 105°C), and current rating (1A per Contact). The primary difference is contact finish (Tin vs. Gold) and active product status.

Q: What are the advantages of Samtec TMM-116 series over the Harwin M22 series? A: Samtec TMM-116 parts offer higher current capacity (3.2A per Contact vs. 1A per Contact) and extended operating temperature range (-55°C ~ 125°C vs. -55°C ~ 105°C). These parts use LCP insulation, which provides superior thermal stability and chemical resistance. However, they use different insulation material (LCP vs. Nylon 6T), which may affect mechanical fit in applications with tight tolerances.

Q: Are there differences between TMM-116-01-F-S, TMM-116-01-L-S, and TMM-116-06-G-S? A: Yes. TMM-116-01-F-S and TMM-116-01-L-S differ in contact finish thickness on the mating surface (3.00µin vs. 10.0µin Gold). TMM-116-06-G-S has longer contact posts (0.192" vs. 0.138") and higher mating surface gold thickness (20.0µin). Select based on specific contact length and finish thickness requirements.

Q: When should TW-16 spacer connectors be used instead of standard headers? A: TW-16 spacer connectors are designed for applications requiring vertical board stacking with defined spacing. Use these parts when multiple PCBs must be stacked with specific gap heights. Standard headers (M22-2011605, M22-2011646, TMM-116 series) are for single-board or direct board-to-board connections without stacking requirements.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed (M22-2011646, TMM-116 series, TW-16 series) are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the difference between contact finish options in TMM-116 parts? A: Contact finish options vary by part number suffix. Gold finishes (F, L, G, S variants) provide superior corrosion resistance and lower contact resistance. Tin finishes (T variant) offer cost reduction but may have slightly higher contact resistance. Select based on application requirements for reliability and cost optimization.
