Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 961124-6300-AR-TP is determined by the following critical parameters:

Core Compatibility Parameters:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 24 — exact match required
• Number of Rows: 1 — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Surface Mount — exact match required
• Termination: Solder — exact match required
• Fastening Type: Push-Pull — exact match required
• Insulation Material: Thermoplastic or equivalent polymer — functionally compatible
• Contact Finish - Mating: Gold — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required

Allowable Variations:

• Contact Length - Mating: Minor variations within 0.210" ± 0.026" (5.33mm ± 0.66mm) are acceptable for board-to-board applications
• Insulation Height: Variations within 0.098" ± 0.002" (2.50mm ± 0.05mm) are acceptable
• Operating Temperature: Extended ranges are acceptable; minimum range must encompass -25°C ~ 105°C
• Current Rating: Equal or higher ratings are acceptable
• Contact Material: Copper Alloy or Phosphor Bronze are functionally equivalent
• Insulation Material: Thermoplastic, Polyamide (PA6T), or Liquid Crystal Polymer (LCP) are acceptable

All substitute parts listed below meet these criteria and maintain functional and mechanical compatibility with the original 3M 961124-6300-AR-TP connector.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Würth Elektronik 61002418221

The Würth Elektronik 61002418221 is the preferred substitute for the obsolete 3M 961124-6300-AR-TP. This part maintains active product status with ROHS3 compliance and REACH unaffected certification. The connector provides a higher current rating of 3A compared to the original 2A specification, and an extended operating temperature range of -40°C ~ 125°C. The contact length variation of 0.236" (6.00mm) versus the original 0.210" (5.33mm) remains within acceptable mechanical tolerances for board-to-board applications. Polyamide (PA6T) insulation material provides equivalent performance to the original thermoplastic construction.

Secondary Recommendations: Samtec TSM Series (TSM-124-01-F-SV, TSM-124-01-L-SV-A-P, TSM-124-01-S-SV-P)

The Samtec TSM series connectors offer active product status with ROHS3 compliance. All three variants feature cuttable header design, extended operating temperature range of -55°C ~ 125°C, and Liquid Crystal Polymer (LCP) insulation material. Contact length specifications of 0.230" (5.84mm) fall within acceptable mechanical tolerances. Differentiation among the three TSM variants is based on contact finish thickness and assembly features:

• TSM-124-01-F-SV: Standard configuration with 3.00µin (0.076µm) contact finish thickness
• TSM-124-01-L-SV-A-P: Includes board guide and pick-and-place features with 10.0µin (0.25µm) contact finish thickness
• TSM-124-01-S-SV-P: Includes pick-and-place feature with 30.0µin (0.76µm) contact finish thickness

Selection among Samtec variants depends on assembly process requirements and board design specifications.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 61002418221 be used as a direct drop-in replacement for the 3M 961124-6300-AR-TP?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (24), row configuration (1), contact type (male pin), mounting method (surface mount), termination (solder), and fastening mechanism (push-pull). The contact length variation of 0.026" (0.66mm) and insulation height difference of 0.002" (0.04mm) are within acceptable mechanical tolerances for board-to-board interconnection. PCB footprint compatibility should be verified during design integration.

Q: What is the difference between the three Samtec TSM variants?

A: All three Samtec TSM variants (TSM-124-01-F-SV, TSM-124-01-L-SV-A-P, TSM-124-01-S-SV-P) are electrically and mechanically equivalent. Differences are limited to assembly features and contact finish thickness. The TSM-124-01-L-SV-A-P includes board guide and pick-and-place features suitable for automated assembly. The TSM-124-01-S-SV-P includes pick-and-place feature only. The TSM-124-01-F-SV is the standard configuration without additional assembly features. Contact finish thickness varies from 3.00µin to 30.0µin across the variants, with no functional impact on connector performance.

Q: Are there any compliance or certification differences between the substitute parts?

A: All substitute parts listed are ROHS3 compliant and carry UL94 V-0 flammability rating. The Würth Elektronik 61002418221 carries REACH unaffected certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity level. The original 3M part is classified as obsolete; all substitutes maintain active product status, ensuring ongoing availability and technical support.

Q: What is the impact of the contact length variation between the original and substitute parts?

A: The original 3M 961124-6300-AR-TP specifies 0.210" (5.33mm) mating contact length. Substitute parts range from 0.230" (5.84mm) to 0.236" (6.00mm). These variations represent 0.020" to 0.026" (0.51mm to 0.66mm) increases. For standard board-to-board applications with typical mating depths of 0.150" to 0.200" (3.81mm to 5.08mm), these variations remain within acceptable mechanical tolerances. PCB layout and mating connector specifications should be reviewed to confirm compatibility.

Q: Can the Samtec TSM series connectors be used in applications requiring the original 2A current rating?

A: The Samtec TSM series datasheets do not specify current rating values. For applications with defined current requirements, the Würth Elektronik 61002418221 with its specified 3A current rating is the recommended choice. Contact Samtec directly for TSM series current rating specifications if required for your application.

Q: What packaging options are available for these substitute parts?

A: The Würth Elektronik 61002418221 is supplied in tube packaging. The Samtec TSM-124-01-F-SV is supplied in tube packaging. The Samtec TSM-124-01-L-SV-A-P and TSM-124-01-S-SV-P do not specify packaging format in the provided data. Packaging specifications should be confirmed with the respective manufacturers for procurement and handling requirements.
