MTSW-102-08-G-D-240 Equivalent & Substitute Parts

Part Overview

The MTSW-102-08-G-D-240 is a rectangular connector header manufactured by Samtec Inc., designed for through-hole mounting applications. This 4-position, 2-row connector operates at 0.100" (2.54mm) pitch and supports board-to-board or cable connections with a 3A current rating. The part is actively produced and widely used in applications requiring reliable vertical header connectivity with push-pull fastening.

Identifying equivalent and substitute parts is necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility permits component standardization across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MTSW-102-08-G-D-240 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Material Flammability Rating: UL94 V-0

The 3M 929665-02-02-I meets all critical mechanical and electrical parameters required for direct substitution. Both parts share identical pitch spacing, position count, row configuration, and contact geometry. Both employ gold-plated mating surfaces, through-hole solder termination, and push-pull fastening mechanisms. Both achieve UL94 V-0 flammability compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the MTSW-102-08-G-D-240 and 929665-02-02-I are active products with current manufacturing status and RoHS compliance certifications. Both achieve UL94 V-0 flammability ratings and employ identical mating pitch, position count, and row spacing.

The 929665-02-02-I presents the following considerations for selection:

The 3M part operates within a narrower temperature range (-40°C to 105°C versus -55°C to 125°C), which may limit suitability for applications requiring extended low-temperature or high-temperature operation.

The 3M part carries a 2.5A current rating compared to the Samtec part's 3A rating. Applications requiring the full 3A capacity must use the MTSW-102-08-G-D-240.

Contact length dimensions differ by up to 0.020" (0.50mm) on the post length. PCB design and mating connector depth must accommodate these variations.

Contact material composition differs (Phosphor Bronze versus Copper Alloy), which may affect long-term contact resistance characteristics in specific environmental conditions.

Both parts employ gold-plated mating surfaces with identical finish thickness and are suitable for push-pull fastening applications.

Frequently Asked Questions (FAQ)

Q: Can the 929665-02-02-I directly replace the MTSW-102-08-G-D-240 in all applications?

A: Direct replacement is possible for applications operating within -40°C to 105°C and requiring maximum 2.5A current. Applications requiring the full 3A capacity or extended temperature range (-55°C to 125°C) must use the MTSW-102-08-G-D-240.

Q: What are the critical parameters that define substitution compatibility?

A: Pitch spacing (0.100"), position count (4), row configuration (2 rows), contact type (male pin), mounting method (through hole), termination (solder), and fastening mechanism (push-pull) must remain identical. Both parts meet these criteria.

Q: Do the contact length differences affect PCB design?

A: Yes. The 929665-02-02-I has a 0.020" (0.50mm) longer post length and 0.015" (0.38mm) greater overall contact length. PCB hole depth and mating connector cavity depth must accommodate these dimensional variations.

Q: Are both parts RoHS compliant?

A: Yes. The MTSW-102-08-G-D-240 is ROHS3 compliant, and the 929665-02-02-I is RoHS compliant. Both meet regulatory requirements for lead-free manufacturing.

Q: What is the difference in contact material composition?

A: The MTSW-102-08-G-D-240 uses Phosphor Bronze contacts, while the 929665-02-02-I uses Copper Alloy contacts. Both employ identical gold plating thickness (10.0µin / 0.25µm) on mating surfaces.

Q: Which part should be selected for high-temperature applications?

A: The MTSW-102-08-G-D-240 supports operation to 125°C, while the 929665-02-02-I is rated to 105°C. For applications exceeding 105°C, the Samtec part is required.

Q: Are both parts actively manufactured?

A: Yes. Both the MTSW-102-08-G-D-240 and 929665-02-02-I maintain active product status with current production.
