• Contact rating: 1 A
• Switching voltage: 28VDC maximum
• Coil current: 40 mA
• Coil resistance: 125 Ohms
• Must operate voltage: 2.6 VDC
• Must release voltage: 0.22 VDC
• Operate time: 3.5 ms
• Release time: 7.5 ms

Mechanical Parameters:

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Hermetically
• Coil type: Non Latching
• Features: Diode

Environmental Parameters:

• Operating temperature range: -65°C to 125°C

All substitute parts maintain identical specifications across these parameters, ensuring direct functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three relay models—1617598, PR1MSPD-5X, and PR1MSCD-5Y—are active production parts manufactured by TE Connectivity Aerospace, Defense and Marine. Each part maintains identical electrical and mechanical specifications, ensuring direct functional interchangeability in circuit applications.

Compliance Considerations:

All parts share identical RoHS non-compliance status, ECCN classification (EAR99), and HTSUS code (8536.41.0050). The PR1MSPD-5X and PR1MSCD-5Y both carry REACH Unaffected status, while the main part 1617598 has undefined REACH status. All parts maintain MSL Level 1 (Unlimited) moisture sensitivity rating.

Inventory Availability:

Selection between these parts may be influenced by current inventory levels. The 1617598 has the highest inventory at 1185 pieces, followed by PR1MSPD-5X at 1132 pieces, and PR1MSCD-5Y at 650 pieces. All parts are available as new original stock in bulk packaging.

Series Differentiation:

The three parts represent different series within the TE Connectivity general purpose relay product line: PR1MSCT (1617598), PR1MSPD (PR1MSPD-5X), and PR1MSCD (PR1MSCD-5Y). Series designation reflects internal design variations that do not affect the specified electrical or mechanical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can PR1MSPD-5X and PR1MSCD-5Y be used interchangeably with 1617598 in existing circuit designs?

A: Yes. All three parts maintain identical coil voltage (5VDC), contact form (SPDT), contact rating (1A), switching voltage (28VDC maximum), coil current (40mA), timing characteristics (3.5ms operate, 7.5ms release), operating temperature range (-65°C to 125°C), and termination style (PC Pin through-hole). Direct substitution is supported without circuit modification.

Q: What are the critical parameters that define substitution eligibility for this relay category?

A: Substitution eligibility is determined by equivalence across coil voltage, contact form, contact current rating, switching voltage, coil current, coil resistance, operate and release times, must-operate and must-release voltages, mounting type, termination style, seal rating, and operating temperature range. All substitute parts maintain identical values for these parameters.

Q: Are there differences in REACH compliance status between the main part and substitutes?

A: The main part 1617598 has undefined REACH status, while both substitute parts PR1MSPD-5X and PR1MSCD-5Y carry REACH Unaffected designation. All parts share identical RoHS non-compliance status and EAR99 ECCN classification.

Q: How do the series designations (PR1MSCT, PR1MSPD, PR1MSCD) affect part selection?

A: Series designations identify different product lines within TE Connectivity's general purpose relay portfolio. Series differences do not affect the specified electrical or mechanical performance parameters. Selection between series may be based on inventory availability, supply chain considerations, or internal design preferences that do not impact circuit functionality.

Q: What is the significance of the MSL Level 1 (Unlimited) rating for these relays?

A: MSL Level 1 indicates unlimited shelf life without moisture sensitivity concerns. These relays do not require special moisture control during storage, handling, or transportation, simplifying inventory management and logistics for aerospace, defense, and marine applications.

Q: Are all three parts suitable for the full operating temperature range specified?

A: Yes. All three parts are rated for identical operating temperature range of -65°C to 125°C, supporting deployment in extreme environmental conditions typical of aerospace, defense, and marine applications.

Q: What is the coil resistance specification, and why is it important for substitution?

A: All three parts maintain 125 Ohms coil resistance. This specification is critical for circuit design calculations, as it determines the coil current draw (40mA at 5VDC) and influences power supply requirements and thermal management considerations.
