TSM-102-01-G-SV-TR Equivalent & Substitute Parts

Part Overview

The TSM-102-01-G-SV-TR is a rectangular connector header manufactured by Samtec Inc., designed for surface mount applications requiring a 2-position, 0.100" (2.54mm) pitch board-to-board or cable connection. This cuttable header connector features unshrouded male pins with gold-plated phosphor bronze contacts and is classified as Active product status. Alternative equivalent parts may be required due to inventory constraints, packaging preferences, or specific application requirements where substitute connectors meet the same electrical and mechanical interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TSM-102-01-G-SV-TR are identified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• Number of Positions: 2
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Contact Finish - Mating: Gold
• Insulation Height: 0.100" (2.54mm)
• RoHS Status: ROHS3 Compliant
• Material Flammability Rating: UL94 V-0

The substitute parts listed below satisfy these core parameters, enabling direct functional replacement in applications where the mating interface and environmental compliance requirements are identical. Variations in contact material, insulation material composition, and operating temperature ranges are noted where they differ from the main part specification.

Parameter Comparison

Engineering Selection Recommendations

M20-8770242 (Harwin Inc.): This part qualifies as a direct equivalent based on matching connector type (Header, Cuttable), contact configuration (2-position male pin), pitch (0.100" / 2.54mm), mounting method (Surface Mount), contact finish (Gold), insulation height (0.100" / 2.54mm), and compliance certifications (ROHS3 Compliant, UL94 V-0). The primary distinction is the operating temperature range (-40°C ~ 105°C versus -55°C ~ 125°C), which narrows the thermal envelope. Selection of this substitute is appropriate for applications operating within the -40°C to +105°C range. Insulation material differs (Polyamide PA6T/Nylon 6T versus LCP), and current rating is specified at 3A per contact.

812-22-002-30-004101 (Mill-Max Manufacturing Corp.): This part shares the 2-position, 0.100" (2.54mm) pitch, surface mount configuration, and gold-plated contact finish. However, the connector type is classified as Piston rather than Header, representing a different mechanical interface design. This part is suitable only for applications where the mating interface is compatible with spring piston contact geometry. RoHS3 compliance and REACH Unaffected status are confirmed; however, operating temperature range and material flammability rating are not specified in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the M20-8770242 be used as a direct replacement for the TSM-102-01-G-SV-TR?

A: The M20-8770242 is functionally equivalent for applications operating within -40°C to +105°C. Both parts share identical pitch (0.100" / 2.54mm), position count (2), mounting type (Surface Mount), contact configuration (male pin), and compliance certifications (ROHS3, UL94 V-0). The TSM-102-01-G-SV-TR supports a wider operating temperature range (-55°C ~ 125°C). Selection depends on your application's thermal requirements.

Q: What is the difference between the Header and Piston connector types?

A: The TSM-102-01-G-SV-TR and M20-8770242 are Header connectors with rigid male pins designed to mate with receptacle sockets. The 812-22-002-30-004101 is a Piston connector featuring spring-loaded contacts. Piston connectors provide different mating force characteristics and are not interchangeable with header connectors unless the mating receptacle is specifically designed for piston contact geometry.

Q: Are there packaging differences between these parts?

A: Yes. The TSM-102-01-G-SV-TR is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Both M20-8770242 and 812-22-002-30-004101 are supplied in Bulk packaging. Packaging selection depends on your manufacturing process requirements and volume handling procedures.

Q: Do all substitute parts meet the same compliance standards?

A: The TSM-102-01-G-SV-TR and M20-8770242 both carry ROHS3 Compliant and UL94 V-0 certifications. The 812-22-002-30-004101 is ROHS3 Compliant and REACH Unaffected; however, material flammability rating is not specified in the provided data. Verify flammability requirements with the manufacturer if this specification is critical for your application.

Q: What contact material differences exist between these parts?

A: The TSM-102-01-G-SV-TR uses Phosphor Bronze contacts, the M20-8770242 uses Brass, and the 812-22-002-30-004101 uses Copper Alloy. All three are gold-plated for corrosion resistance. Contact material affects mechanical durability and electrical conductivity; however, all three materials are suitable for standard signal and low-power applications at the specified pitch and contact configuration.
