Parameter Comparison

Engineering Selection Recommendations

The part 1-1825013-2 is a direct functional equivalent to the MRD16C across all critical electrical, mechanical, and material specifications. The primary distinction is product status: the MRD16C is obsolete, while 1-1825013-2 is active and currently manufactured.

Selection Basis:

1. Product Status: The MRD16C is classified as obsolete. The 1-1825013-2 maintains active production status, ensuring long-term availability and supply chain continuity.

2. Electrical Equivalence: Both parts operate identically within the specified 20VAC/DC, 0.4VA rating across 16 hexadecimal complement positions.

3. Mechanical Compatibility: Identical through-hole mounting, pitch, height, and form factor ensure direct PCB layout compatibility without redesign.

4. Operating Temperature: The 1-1825013-2 provides an extended lower operating temperature limit (-30°C versus -10°C), offering improved performance in cold environments without compromising upper temperature capability.

5. Compliance & Certifications: Both parts share identical ECCN (EAR99) and HTSUS classifications. The 1-1825013-2 carries active product status with consistent regulatory treatment.

For new designs and production transitions, 1-1825013-2 is the appropriate selection. For legacy system maintenance where MRD16C inventory is depleted, 1-1825013-2 provides direct substitution without functional or physical modification.

Frequently Asked Questions (FAQ)

Q: Can 1-1825013-2 replace MRD16C in existing designs?

A: Yes. The 1-1825013-2 is electrically and mechanically equivalent to the MRD16C. All critical parameters—circuit type, position count, voltage/current ratings, actuator type, mounting configuration, and physical dimensions—are identical. Direct substitution is possible without PCB or schematic modification.

Q: What is the primary reason to transition from MRD16C to 1-1825013-2?

A: The MRD16C is obsolete and no longer manufactured. The 1-1825013-2 is an active product from the same manufacturer and series, ensuring continued availability, supply chain reliability, and manufacturer support.

Q: Are there differences in contact material or finish?

A: No. Both parts use beryllium copper contacts with gold finish, ensuring identical electrical performance and reliability characteristics.

Q: Does the operating temperature difference affect substitution?

A: The 1-1825013-2 has an extended lower operating temperature range (-30°C to 85°C versus -10°C to 85°C). This represents an improvement and does not restrict substitution. Applications operating within the original -10°C to 85°C range will function identically in both parts.

Q: Are the mechanical life and electrical life ratings the same?

A: Yes. Both parts are rated for 20,000 mechanical steps and 10,000 electrical steps, providing identical durability and cycle life performance.

Q: Is the through-hole pitch identical?

A: Yes. Both parts use 0.100" (2.54mm) pitch with full spacing, ensuring direct compatibility with existing PCB footprints without modification.

Q: Are there any compliance or regulatory differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications. Regulatory treatment is consistent between the two parts.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
