Engineering Selection Recommendations

All substitute parts listed maintain Active product status and comply with RoHS regulations, ensuring regulatory alignment with the primary part 826646-9. Selection among substitute parts should be based on the following compliance and certification factors:

RoHS Compliance Considerations: The 826646-9 carries RoHS Compliant status. Substitute parts 0901200129, 61300911121, M20-9990945, and TSW-109-24-G-S are ROHS3 Compliant, representing updated compliance standards. Part A2-9PA-2.54DSA(71) maintains RoHS Compliant status matching the original part.

Flammability and Safety: All substitute parts maintain UL94 V-0 material flammability rating, ensuring equivalent safety performance in applications requiring flame resistance.

Moisture Sensitivity: The primary part and most substitute parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements. Part 61300911121 carries Not Applicable MSL status, also acceptable for standard handling.

Temperature Operating Range: The 826646-9 operates from -65°C to 105°C. Substitute parts operate within ranges of -55°C to 125°C (0901200129, A2-9PA-2.54DSA(71), TSW-109-24-G-S), -40°C to 105°C (61300911121, M20-9990945), or -55°C to 85°C (A2-9PA-2.54DSA(71)). Applications requiring the full -65°C lower temperature limit of the original part should reference the primary 826646-9 specification.

Current Rating Considerations: The 826646-9 specifies 5A current rating. Substitute parts 61300911121, A2-9PA-2.54DSA(71), and M20-9990945 specify 3A current rating. Applications requiring 5A per contact should reference the primary part or substitute parts with unspecified current ratings (0901200129, TSW-109-24-G-S).

Contact Finish Specifications: The 826646-9 features gold-plated mating contacts with tin-plated posts. Substitute parts vary in contact finish: 0901200129 uses tin mating finish; 61300911121 and M20-9990945 use gold mating finish; TSW-109-24-G-S uses gold on both mating and post surfaces. Contact finish selection depends on application-specific corrosion resistance and signal integrity requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 826646-9 with any of the listed parts directly?

A: All listed substitute parts share the critical parameters that define functional equivalence: 9-position, 1-row configuration with 0.100" (2.54mm) pitch, male pin contacts, through-hole solder termination, and push-pull fastening. Direct substitution is mechanically and electrically feasible. However, verify application-specific requirements for current rating, operating temperature range, and contact finish specifications before final selection.

Q: What is the significance of the contact finish differences between parts?

A: Contact finish affects corrosion resistance, signal integrity, and mating force characteristics. The 826646-9 uses gold-plated mating contacts for superior corrosion resistance and low contact resistance. Substitute part 0901200129 uses tin plating, which provides adequate performance in standard environments but may not match the corrosion resistance of gold-plated contacts. Parts with gold mating finishes (61300911121, A2-9PA-2.54DSA(71), M20-9990945, TSW-109-24-G-S) provide equivalent corrosion resistance to the original part.

Q: Why do some substitute parts have lower current ratings than the 826646-9?

A: Current rating depends on contact material, contact geometry, and insulation material thermal properties. The 826646-9 specifies 5A per contact, while parts 61300911121, A2-9PA-2.54DSA(71), and M20-9990945 specify 3A per contact. Applications requiring 5A per contact should use the 826646-9 or substitute parts with unspecified current ratings. For applications requiring 3A or less, the lower-rated parts are suitable.

Q: Are there temperature range limitations I should consider?

A: The 826646-9 operates from -65°C to 105°C. Substitute part A2-9PA-2.54DSA(71) has a lower maximum temperature limit of 85°C, making it unsuitable for applications exceeding 85°C. Parts 61300911121 and M20-9990945 operate to 105°C maximum, matching the original part. Parts 0901200129 and TSW-109-24-G-S extend to 125°C maximum. For applications requiring the full -65°C lower limit, the 826646-9 is the only option; other parts operate to -55°C or -40°C minimum.

Q: What does the "Breakaway" or "Cuttable" connector type designation mean?

A: These designations indicate the connector header can be separated into individual positions or smaller groups. The 826646-9 is designated as "Header, Breakaway," allowing the 9-position header to be broken into smaller configurations. Part M20-9990945 is designated "Header, Cuttable," indicating similar functionality. This feature provides design flexibility for applications requiring fewer than 9 positions without requiring a different part number.

Q: How do insulation material differences affect part selection?

A: The 826646-9 uses Polybutylene Terephthalate (PBT), a thermoplastic with good electrical properties and dimensional stability. Substitute parts use PBT, Polyester Glass Filled, or Polyamide (PA6T/Nylon 6T). All materials maintain UL94 V-0 flammability rating. Polyamide materials (61300911121, M20-9990945) offer slightly higher temperature capability and mechanical strength. Polyester Glass Filled (0901200129) provides enhanced dimensional stability. For standard applications, all materials are functionally equivalent.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 Directive (2015/863/EU), which includes additional restricted substances. Both statuses are acceptable for regulatory purposes. ROHS3 Compliant parts (0901200129, 61300911121, M20-9990945, TSW-109-24-G-S) represent current compliance standards.

Q: Can I use these parts interchangeably in existing designs?

A: Mechanical and electrical interchangeability is established across all listed parts for the core connector function. However, verify the following before implementation: (1) PCB footprint compatibility, as contact length and insulation height variations may affect board layout; (2) mating connector compatibility, as contact finish and geometry variations may affect mating force and contact resistance; (3) application current and temperature requirements, as rated specifications vary among parts; (4) supply chain and cost considerations, as inventory levels and pricing differ by manufacturer.
