IM04JR Telecom Relay DPDT Equivalent & Substitute Parts

Part Overview

The IM04JR is a Surface Mount telecom relay manufactured by TE Connectivity Potter & Brumfield Relays, classified within the IM and AXICOM series. This DPDT (2 Form C) relay operates at 6VDC with a 2A contact rating and is designed for telecom switching applications. The part is Active in product status and available in Tape & Reel packaging with 685 pieces in current inventory.

Equivalent and substitute parts are identified when design requirements permit relaxation of specific electrical parameters while maintaining core functional compatibility. Substitution becomes necessary when the primary part reaches end-of-life status, inventory constraints occur, or alternative sourcing strategies are implemented.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IM04JR is evaluated based on the following critical parameters that define functional equivalence:

Core Compatibility Parameters:

• Coil Voltage: 6VDC (exact match required)
• Contact Form: DPDT (2 Form C) (exact match required)
• Coil Type: Non Latching (exact match required)
• Coil Current: 23.3 mA (exact match required)
• Coil Resistance: 257 Ohms (exact match required)
• Must Operate Voltage: 4.5 VDC (exact match required)
• Must Release Voltage: 0.6 VDC (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Relay Type: Telecom (exact match required)

Parameters Permitting Variation:

• Contact Rating (Current): Substitutes with equal or higher current rating are acceptable
• Switching Voltage: Substitutes with equal or higher switching voltage are acceptable
• Termination Style: Variation permitted based on PCB design compatibility
• Packaging Format: Variation permitted based on procurement and assembly requirements
• Seal Rating: Variation permitted when application requirements are met

The AGN200S06 meets all core compatibility parameters. The contact rating of 1A is lower than the IM04JR specification of 2A, and the switching voltage of 125VAC/110VDC is lower than the IM04JR specification of 250VAC/220VDC. These differences restrict the AGN200S06 to applications with reduced current and voltage demands.

Parameter Comparison

Engineering Selection Recommendations

IM04JR Selection Criteria: The IM04JR is the primary specification when applications require 2A contact rating and 250VAC/220VDC switching voltage capability. This part maintains Active product status with established supply availability (685 pieces in inventory). The IM04JR carries ROHS3 compliance, meeting the highest regulatory standard. Hermetic sealing provides enhanced environmental protection for demanding telecom applications.

AGN200S06 Selection Criteria: The AGN200S06 is suitable as a substitute only when application requirements permit reduced contact rating (1A maximum) and reduced switching voltage (125VAC/110VDC maximum). This part is Active in product status with higher inventory availability (1,300 pieces). The AGN200S06 carries RoHS compliance and provides full sealing. The Gull Wing termination requires PCB footprint modification compared to the J Lead termination of the IM04JR. The 1 millisecond increase in operate and release times must be evaluated against timing-critical circuit requirements.

Compliance Considerations: Both parts carry EAR99 ECCN classification and share identical HTSUS coding (8536.41.0020). The IM04JR provides superior regulatory compliance through ROHS3 certification. Both parts are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can the AGN200S06 directly replace the IM04JR without PCB modification?

A: No. The AGN200S06 uses Gull Wing termination while the IM04JR uses J Lead termination. PCB footprint modification is required. Additionally, the different contact material composition and reduced electrical ratings necessitate circuit validation.

Q: What are the electrical limitations when substituting with AGN200S06?

A: The AGN200S06 is limited to 1A maximum contact current (versus 2A for IM04JR) and 125VAC/110VDC maximum switching voltage (versus 250VAC/220VDC for IM04JR). Applications exceeding these ratings cannot use the AGN200S06.

Q: Does the 1 millisecond timing difference between parts affect circuit operation?

A: The AGN200S06 operates and releases 1 millisecond slower than the IM04JR (4 ms versus 3 ms). Timing-critical applications must evaluate whether this difference impacts system performance.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both the IM04JR and AGN200S06 operate across the identical temperature range of -40°C to 85°C.

Q: What is the difference in sealing between these parts?

A: The IM04JR features hermetic sealing, providing the highest level of environmental protection. The AGN200S06 features full sealing, which provides adequate protection for most applications but does not meet hermetic specifications.

Q: Which part has better regulatory compliance?

A: The IM04JR carries ROHS3 compliance, which is the highest RoHS standard. The AGN200S06 carries standard RoHS compliance. Both are REACH Unaffected and carry EAR99 ECCN classification.

Q: Can I use AGN200S06 in a design originally specified for IM04JR?

A: Only if the application requirements permit reduced current rating (1A or less) and reduced switching voltage (125VAC/110VDC or less), PCB footprint can be modified for Gull Wing termination, and the 1 millisecond timing increase is acceptable. Full circuit validation is required.

Q: What packaging formats are available for each part?

A: The IM04JR is supplied in Tape & Reel (TR) packaging. The AGN200S06 is supplied in Tube packaging. Procurement and assembly processes must accommodate these different formats.

Q: Do both parts use the same coil specifications?

A: Yes. Both parts share identical coil voltage (6VDC), coil current (23.3 mA), coil resistance (257 Ohms), and coil type (Non Latching). Both require 4.5VDC to operate and 0.6VDC to release.
