Parameter Comparison

Engineering Selection Recommendations

All three part numbers—1617542-1, 9-1617351-9, and JMACDG-12XM—are active production parts manufactured by TE Connectivity Aerospace, Defense and Marine within the MAC series. Each part is identical in electrical performance, mechanical configuration, and environmental specifications. Selection among these equivalents is based on the following factors:

Product Status: All parts maintain active production status, ensuring continued availability and support.

Compliance & Certifications: All parts share identical RoHS non-compliance status and REACH unaffected classification. Moisture sensitivity level is uniform at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Inventory Availability: Part 1617542-1 has the highest current inventory at 944 units. Part 9-1617351-9 has 802 units in stock. Part JMACDG-12XM has 636 units available. Selection may be influenced by procurement lead times and supply chain requirements.

Functional Interchangeability: These parts are direct functional equivalents with no performance differentiation. Circuit-level performance, switching characteristics, and thermal behavior are identical across all three part numbers.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable in circuit applications?

A: Yes. The parts 1617542-1, 9-1617351-9, and JMACDG-12XM are parametric equivalents with identical electrical specifications. They share the same coil voltage (12VDC), contact rating (1A), switching voltage (115VAC, 28VDC - Max), coil current (30.8 mA), and timing characteristics (2 ms operate, 4 ms release). Direct substitution in existing circuit designs is supported without modification.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching across coil voltage, contact form (DPDT), contact current rating, switching voltage, coil resistance, operating temperature range, mounting type (through hole), termination style (PC pin), seal rating (hermetically sealed), and contact material composition. All three parts match these parameters without exception.

Q: Do these relays require special handling during storage or assembly?

A: No. All three parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures for electronic components are sufficient.

Q: Are there any compliance or regulatory differences between these part numbers?

A: No. All three parts share identical RoHS non-compliance status and REACH unaffected classification. Regulatory and compliance profiles are uniform across all substitute options.

Q: Can these parts be used in aerospace, defense, and marine applications?

A: Yes. All parts are manufactured by TE Connectivity Aerospace, Defense and Marine and are rated for operating temperatures from -65°C to 125°C with hermetic sealing. These specifications support deployment in demanding aerospace, defense, and marine environments.

Q: What is the difference between part number formats (1617542-1 vs. 9-1617351-9 vs. JMACDG-12XM)?

A: The different part number formats reflect internal TE Connectivity numbering conventions and product line designations. Functionally and electrically, all three parts are identical. The variation in part number structure does not indicate performance differences or application restrictions.

Q: Which part should be selected if all three are available?

A: Selection is based on procurement requirements and inventory availability. Part 1617542-1 has the highest current stock (944 units), followed by 9-1617351-9 (802 units) and JMACDG-12XM (636 units). For applications with no specific part number requirement, selection based on availability and lead time is appropriate.

Q: Are these parts suitable for high-reliability applications?

A: Yes. All parts feature hermetic sealing, silver palladium and gold contact materials, integrated diode protection, and non-latching coil design. These characteristics support high-reliability switching applications in demanding environments.
