Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with RoHS requirements, ensuring regulatory compliance and long-term availability. Selection among these alternatives depends on specific application constraints:

TE Connectivity 2-826632-5 (Primary Part): Offers the highest current rating (5A) and the widest operating temperature range (-65°C to 105°C). The breakaway connector type provides design flexibility. Brass contact material with gold mating finish and tin post finish delivers standard performance characteristics.

Hirose A1-50PA-2.54DSA(71): Operates within a narrower temperature range (-55°C to 85°C) and supports 3A current rating. Insulation height is reduced to 0.100" (2.54mm) compared to the primary part. ROHS3 compliance and tray packaging provide alternative supply chain options.

Harwin M20-9982545: Features a cuttable connector type and operates across -40°C to 105°C with 3A per contact rating. Polyamide (PA6T) insulation material differs from PBT alternatives. ROHS3 compliance and bulk packaging support high-volume applications.

Samtec TSW-125-24-G-D: Supports the highest operating temperature range (-55°C to 125°C) with phosphor bronze contact material. Gold plating on both mating and post contacts provides enhanced corrosion resistance. ROHS3 compliance and bulk packaging are standard.

Samtec TSW-125-24-S-D: Operates across -55°C to 125°C with phosphor bronze contacts. Gold mating finish (30.0µin thickness) and tin post finish balance performance and cost. ROHS3 compliance and bulk packaging support production environments.

Samtec TSW-125-24-T-D: Operates across -55°C to 105°C with tin finish on both mating and post contacts. Phosphor bronze contact material and PBT insulation provide standard reliability. ROHS3 compliance and bulk packaging are standard.

Frequently Asked Questions (FAQ)

Q: What are the primary compatibility criteria for substituting the TE Connectivity 2-826632-5?

A: The substitute parts must maintain 50 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, male pin contacts, solder termination, push-pull fastening, and unshrouded design. All listed alternatives meet these core requirements.

Q: How do contact length variations affect substitution?

A: Contact length differences impact mating depth and overall connector height. The TE Connectivity part features 0.264" (6.70mm) mating contact length and 0.500" (12.70mm) overall length. Samtec alternatives provide 0.265" (6.73mm) mating length and 0.480" (12.19mm) overall length. Hirose and Harwin parts feature shorter mating contacts (0.236" and 0.240" respectively). These variations require PCB layout verification to ensure proper mating alignment.

Q: What is the significance of the current rating difference between the primary part and substitutes?

A: The TE Connectivity 2-826632-5 supports 5A per contact, while Hirose and Harwin alternatives support 3A per contact. Samtec parts do not specify current ratings. Applications requiring 5A per contact must use the primary part or verify that lower current ratings are acceptable for the intended design.

Q: How do operating temperature ranges differ among the alternatives?

A: The TE Connectivity part operates from -65°C to 105°C, providing the lowest minimum temperature. Hirose operates -55°C to 85°C (most restricted range). Harwin operates -40°C to 105°C. Samtec TSW-125-24-G-D and TSW-125-24-S-D operate -55°C to 125°C (highest maximum). TSW-125-24-T-D operates -55°C to 105°C. Application temperature requirements determine which alternatives are suitable.

Q: What is the difference between brass and phosphor bronze contact materials?

A: The TE Connectivity part uses brass contacts, while Samtec alternatives use phosphor bronze. Phosphor bronze provides enhanced spring characteristics and wear resistance. Both materials are suitable for standard through-hole applications. Material selection depends on contact force requirements and expected mating cycles.

Q: How do contact finish specifications affect connector performance?

A: The TE Connectivity part features gold-plated mating contacts (3.90µin thickness) and tin-plated posts. Samtec TSW-125-24-G-D provides gold on both mating and post surfaces. TSW-125-24-S-D provides gold mating (30.0µin) and tin posts. TSW-125-24-T-D provides tin on both surfaces. Gold plating enhances corrosion resistance and contact reliability, while tin plating reduces cost. Selection depends on environmental exposure and reliability requirements.

Q: What packaging options are available?

A: The TE Connectivity part is supplied in bulk packaging. Hirose A1-50PA-2.54DSA(71) is supplied in tray packaging. Harwin M20-9982545 and all Samtec alternatives are supplied in bulk packaging. Packaging selection affects handling, storage, and automated assembly compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TE Connectivity part is RoHS Compliant. All substitute parts are ROHS3 Compliant, which represents the current RoHS standard. All parts meet regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: All parts, including the primary and all substitutes, carry MSL 1 (Unlimited) rating. This indicates no moisture sensitivity precautions are required during storage, handling, or assembly. Parts can be stored in standard industrial environments without desiccant packaging or controlled humidity conditions.

Q: Can the Harwin M20-9982545 cuttable feature be used interchangeably with the TE Connectivity breakaway design?

A: The cuttable feature allows individual positions to be separated after assembly, while the breakaway design provides pre-scored separation points. Both designs support 50-position configurations with identical pitch and row spacing. The cuttable feature provides additional flexibility for custom configurations but requires different assembly processes. Mechanical compatibility is maintained, but assembly procedures differ.

Q: How does insulation height variation affect board layout?

A: The TE Connectivity part features 0.110" (2.79mm) insulation height, while most substitutes feature 0.100" (2.54mm). This 0.010" (0.25mm) difference affects clearance above the PCB surface. Applications with height-constrained designs may require the lower-profile alternatives. PCB layout and component placement must account for these variations.
