Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2600-03-R is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Must be a header with male pin contacts
• Pitch and Position Count: Must maintain 0.100" (2.54mm) mating pitch with exactly 3 positions in a single row
• Mounting & Orientation: Must support through-hole, right-angle mounting
• Shrouding & Fastening: Must feature shrouded design with friction lock fastening
• Termination Method: Must use solder termination
• Electrical Ratings: Must meet or exceed 250V voltage rating
• Material & Compliance: Must use brass contacts with tin finish, polyamide insulation, and maintain UL94 V-0 and ROHS3 compliance

The substitute part SWR25X-NRTC-S03-RB-BA from Sullins Connector Solutions satisfies all critical substitution parameters within the allowed mechanical and electrical tolerances for this rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the 2600-03-R and SWR25X-NRTC-S03-RB-BA maintain active product status and full compliance with ROHS3 and REACH requirements. Both connectors carry UL94 V-0 material flammability certification and are classified as MSL 1 (Unlimited moisture sensitivity level), indicating no special handling requirements during storage or assembly.

The SWR25X-NRTC-S03-RB-BA substitute provides higher current rating capacity (5A per contact versus 3A) and maintains identical voltage rating (250V), mechanical dimensions, and contact configuration. The mating contact length difference (0.303" versus 0.293") falls within acceptable mechanical tolerance for this connector category and does not affect functional compatibility in standard board-to-cable/wire applications.

Selection between these parts should be based on availability, lead time, and supply chain requirements, as both meet the specified electrical and mechanical parameters for rectangular connector header applications.

Frequently Asked Questions (FAQ)

Q: Can the SWR25X-NRTC-S03-RB-BA directly replace the 2600-03-R in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (3), mounting type (through-hole right-angle), shrouding configuration (shrouded 1-wall), and termination method (solder). The contact post length (0.134" / 3.40mm) is identical, ensuring PCB footprint compatibility.

Q: What is the significance of the mating contact length difference?

A: The 2600-03-R has a mating contact length of 0.293" (7.45mm), while the SWR25X-NRTC-S03-RB-BA measures 0.303" (7.70mm). This 0.010" (0.25mm) difference is within standard mechanical tolerance for rectangular connectors and does not affect mating depth or electrical performance in board-to-cable/wire applications.

Q: Are there any current rating considerations when substituting?

A: The SWR25X-NRTC-S03-RB-BA is rated for 5A per contact, compared to the 2600-03-R at 3A. The substitute part supports higher current capacity, making it suitable for applications requiring the original 3A rating and those requiring up to 5A per contact.

Q: Do both connectors require special handling during assembly?

A: No. Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity level restrictions. Standard PCB assembly processes apply without special baking or desiccant storage requirements.

Q: Are there insulation color differences between these parts?

A: Yes. The 2600-03-R features ivory insulation, while the SWR25X-NRTC-S03-RB-BA uses beige insulation. Both use identical polyamide (PA66) nylon 6/6 material with UL94 V-0 flammability rating. Insulation color does not affect electrical or mechanical function.

Q: What compliance certifications apply to both parts?

A: Both connectors are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 material flammability certification. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040 for export and tariff purposes.
