Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1756530000 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (10A IEC/UL), voltage rating (250V IEC / 150V UL)
• Physical Configuration: 16 positions, 8 positions per level, 2 levels, 4.6mm pitch
• Mechanical Design: Vertical orientation, male pins, 4-side shrouded housing, through-hole mounting
• Termination Method: Solder termination
• Compliance Standards: UL94 V-0 flammability rating, RoHS compliance, IP10 ingress protection
• Operating Environment: Temperature range -50°C to 100°C

The substitute part 1729000000 maintains identical electrical, mechanical, and dimensional specifications. The primary distinction is product status (active versus obsolete) and contact mating finish (tin versus gold), neither of which affects functional interchangeability within the specified electrical and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1729000000 is a direct functional equivalent to the obsolete 1756530000 for applications requiring a 16-position, 4.6mm pitch terminal block header with vertical through-hole mounting and 10A/250V (IEC) electrical ratings.

Product Status Consideration: The 1729000000 maintains active product status, ensuring continued availability, technical support, and supply chain reliability compared to the obsolete 1756530000.

Compliance Alignment: Both parts maintain identical UL94 V-0 flammability certification, RoHS compliance, and IP10 ingress protection ratings, satisfying equivalent regulatory and environmental requirements.

Contact Finish Difference: The 1756530000 features gold contact mating finish, while the 1729000000 uses tin finish. Both finishes are compatible with standard solder termination processes and do not affect electrical performance within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1729000000 directly replace the 1756530000 in existing designs?

A: Yes. Both parts are identical across all critical electrical, mechanical, and dimensional parameters. The 1729000000 is functionally equivalent and maintains the same 16-position configuration, 4.6mm pitch, vertical orientation, and 10A/250V electrical ratings.

Q: What is the significance of the different contact mating finishes?

A: The 1756530000 uses gold finish while the 1729000000 uses tin finish. Both finishes are suitable for solder termination and do not affect electrical performance within the specified operating parameters. Contact finish selection is typically driven by cost and corrosion resistance requirements in specific environmental conditions.

Q: Why is the 1756530000 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 1729000000 provides an active alternative with identical specifications, ensuring continued availability and supply chain support.

Q: Are there packaging differences between these parts?

A: The 1756530000 is listed with unspecified packaging, while the 1729000000 is supplied in bulk packaging. Both parts are functionally identical; packaging differences relate only to order quantity and handling.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1756530000 and 1729000000 are RoHS compliant, UL94 V-0 rated, and maintain IP10 ingress protection. They satisfy identical regulatory and environmental compliance requirements.
