Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on strict alignment with the following critical parameters:

• Pitch and Position Configuration: 0.079" (2.00mm) pitch, 16 positions, 2 rows
• Connector Style: Board-to-board or board-to-cable applications
• Contact Type: Male pin headers
• Mounting Method: Through-hole solder termination
• Electrical Performance: Current rating and contact material compatibility
• Environmental Compliance: RoHS3 compliance and operating temperature range
• Physical Compatibility: Overall contact length and insulation height within acceptable tolerance ranges

Substitutes are divided into two categories:

Category A - Direct Header Substitutes (951216-8622-AR, MTMM-108 series, TMM-108 series): These maintain the core header functionality with equivalent pitch, position count, and through-hole mounting. Variations in contact length and insulation material are acceptable where overall dimensions remain compatible with PCB layouts.

Category B - Stacking Header Substitutes (TW-08 series): These are board stacking connectors with integrated spacer functionality, suitable for applications requiring vertical board separation while maintaining the same pitch and position configuration.

Parameter Comparison

Engineering Selection Recommendations

951216-8622-AR (3M): This substitute offers extended operating temperature range (-55°C to 125°C) and equivalent current rating. The thermoplastic insulation material differs from the original polyamide, but maintains UL94 V-0 flammability compliance. RoHS compliance is confirmed. This part is suitable for applications requiring broader temperature performance.

MTMM-108 Series (Samtec Inc.): All four variants (MTMM-108-02-G-D-115, MTMM-108-03-L-D-138, MTMM-108-04-L-D-120, MTMM-108-07-G-D-150) are cuttable headers with enhanced current ratings (3A per contact) and extended operating temperature (-55°C to 125°C). Liquid Crystal Polymer insulation provides superior thermal and mechanical properties. All variants maintain ROHS3 compliance and MSL 1 rating. Selection among these variants depends on specific contact length and post length requirements for your PCB layout.

TMM-108 Series (Samtec Inc.): TMM-108-01-L-D and TMM-108-02-L-D are non-cuttable headers with 3.2A per contact current rating and -55°C to 125°C operating range. Liquid Crystal Polymer insulation and ROHS3 compliance are confirmed. Material flammability rating is not specified for these variants. These parts are suitable for fixed 16-position applications.

TW-08 Series (Samtec Inc.): TW-08-03-G-D-126-150 and TW-08-11-G-D-140-085 are board stacking connectors with integrated spacer functionality. These are applicable only when vertical board separation is required. Both maintain ROHS3 compliance and MSL 1 rating. Selection between these variants depends on required stack height and pin length specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the M22-2020805 with any of these parts directly?

A: Direct substitution depends on your application's specific requirements. All listed parts share the same 0.079" (2.00mm) pitch, 16-position, 2-row configuration and through-hole solder termination. However, differences in contact length, insulation material, and current rating must be evaluated against your PCB layout and electrical load specifications.

Q: What is the main difference between the MTMM-108 and TMM-108 series?

A: MTMM-108 headers are cuttable, allowing customization of the connector length for specific applications. TMM-108 headers are fixed 16-position connectors. Both series offer higher current ratings (3A and 3.2A respectively) compared to the original M22-2020805 (1A per contact) and operate across -55°C to 125°C.

Q: When should I use the TW-08 series instead of standard headers?

A: The TW-08 series provides integrated board stacking functionality with defined stack heights. Use these connectors when your application requires vertical separation between PCBs while maintaining the same pitch and position configuration. Standard headers do not provide this stacking capability.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant. The original M22-2020805 and most substitutes are ROHS3 compliant. The 3M 951216-8622-AR is RoHS compliant. TMM-108 series parts do not specify flammability rating, while all other parts maintain UL94 V-0 certification.

Q: What is the difference in operating temperature range?

A: The original M22-2020805 operates from -40°C to 105°C. All substitute parts extend this range to -55°C to 125°C, providing broader environmental compatibility for demanding applications.

Q: Can I use a higher current-rated substitute in place of the M22-2020805?

A: Yes. The MTMM-108 series (3A), TMM-108 series (3.2A), and 951216-8622-AR (1A) are all suitable for applications where the original 1A per contact rating is sufficient. Higher current ratings provide design margin and do not create compatibility issues in lower-current applications.

Q: What insulation material differences exist among the substitutes?

A: The original M22-2020805 uses Polyamide (PA6T) Nylon 6T. The 3M 951216-8622-AR uses Thermoplastic. Samtec MTMM-108 and TMM-108 series use Liquid Crystal Polymer (LCP), which offers superior thermal stability and mechanical properties. All materials maintain required flammability ratings for their respective parts.

Q: Are there inventory considerations for these substitutes?

A: All substitute parts are in stock with quantities ranging from 678 to 2067 units. The MTMM-108-07-G-D-150 and 951216-8622-AR offer the highest inventory levels (2067 and 2054 units respectively), providing supply chain flexibility.
