Engineering Selection Recommendations
All substitute parts listed maintain functional compatibility with the 3M 951106-4620-AR-TP based on core electrical and mechanical parameters. Selection among alternatives should prioritize product status and compliance certifications:
Active Product Status: All substitute parts carry active product status, ensuring ongoing availability and manufacturer support. The original 3M part is obsolete, making substitution necessary for new designs and ongoing production.
Compliance Certifications: Samtec MMT series parts (MMT-106-01-F-SH, MMT-106-01-F-SH-A, MMT-106-01-F-SH-A-TR, MMT-106-01-F-SH-K-TR, MMT-106-01-F-SH-P-TR, MMT-106-01-F-SH-TR, MMT-106-01-FM-SH, MMT-106-01-H-SH) carry ROHS3 compliance. Amphenol ICC 10112684-G03-06ULF carries RoHS compliance. Harwin M22-5330605 carries ROHS3 compliance. All parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications.
Packaging Considerations: Samtec parts are available in multiple packaging formats (Tube, Bulk, Tape & Reel). Amphenol ICC part is supplied in Tube packaging. Harwin part is supplied in Bulk packaging. Selection should align with assembly process requirements and inventory management practices.
Current Rating Enhancement: Substitute parts offer current ratings of 2A to 3A, exceeding the original 1A specification. This provides design margin for applications requiring higher current capacity.
Frequently Asked Questions (FAQ)
Q: Can the Samtec MMT-106-01-F-SH directly replace the 3M 951106-4620-AR-TP?
A: Yes. Both parts share identical pitch (0.079" / 2.00mm), position count (6), row configuration (1), mounting type (surface mount right angle), connector type (header), contact type (male pin), termination (solder), and fastening type (push-pull). The Samtec part is active and RoHS3 compliant, addressing the obsolescence of the 3M part.
Q: What is the difference between Samtec MMT-106-01-F-SH and MMT-106-01-F-SH-A?
A: Both parts are electrically and mechanically identical. The primary difference is packaging: MMT-106-01-F-SH is supplied in Tube packaging, while MMT-106-01-F-SH-A is supplied in Bulk packaging. The "-A" designation indicates the addition of a board guide feature. Selection depends on assembly process requirements and handling preferences.
Q: Are the Samtec Tape & Reel variants (MMT-106-01-F-SH-K-TR, MMT-106-01-F-SH-P-TR, MMT-106-01-F-SH-TR) suitable for automated pick-and-place assembly?
A: Yes. All three Tape & Reel variants are compatible with automated assembly equipment. MMT-106-01-F-SH-K-TR and MMT-106-01-F-SH-P-TR include pick-and-place features. Selection among these variants should align with specific assembly equipment specifications and feeder compatibility.
Q: How do the operating temperature ranges compare?
A: The original 3M part operates from -25°C to 105°C. Samtec MMT series parts operate from -55°C to 125°C, providing extended low-temperature and high-temperature capability. Amphenol ICC part operates from -55°C to 125°C. Harwin part operates from -40°C to 105°C. All alternatives meet or exceed the original specification.
Q: What is the significance of the contact finish differences?
A: The 3M part features gold flash finish on mating contacts. Samtec parts feature 3.00µin (0.076µm) gold finish on mating contacts, except MMT-106-01-H-SH which features 30.0µin (0.76µm) gold finish. Amphenol ICC part features 30.0µin (0.76µm) gold or GXT™ finish. All finishes provide equivalent corrosion resistance and electrical performance for the specified application.
Q: Is the Harwin M22-5330605 cuttable feature relevant for this application?
A: The Harwin part includes a cuttable header feature, allowing position reduction if required. This feature is optional and does not affect compatibility with the standard 6-position configuration. Selection of the Harwin part should be based on whether this feature provides value for the specific application.
Q: What compliance certifications apply to all substitute parts?
A: All substitute parts meet UL94 V-0 material flammability requirements and MSL 1 (unlimited) moisture sensitivity specifications. Samtec, Amphenol ICC, and Harwin parts carry RoHS or ROHS3 compliance. ECCN classification is EAR99 for all parts. HTSUS code is 8536.69.4040 for all parts.
