Substitute Part Grouping Explanation

Substitution of the V23079G2011B301 is determined by strict equivalence across the following critical parameters: coil voltage (4.5VDC), contact form (DPDT), contact rating (2A), coil current (31.1 mA), coil resistance (145 Ohms), must operate voltage (3.38 VDC), must release voltage (0.45 VDC), mounting type (Surface Mount), and termination style (Gull Wing). Parts are grouped into three categories based on substitution relationship:

Parametric Equivalent (Packaging Variant): V23079D2011B301 differs only in packaging format (Cut Tape versus Tape & Reel) and RoHS certification level (ROHS3 Compliant versus RoHS Compliant). All electrical and mechanical parameters are identical.

Direct Manufacturer Equivalent (Cross-Manufacturer): TX2SS-4.5V from Panasonic Electric Works meets all critical electrical parameters with identical coil voltage, contact form, contact rating, coil current, coil resistance, and timing specifications. Switching voltage specification differs (220VDC maximum versus 250VAC/220VDC maximum), and seal rating is Sealed - Fully. Packaging is Tube format.

Similar Equivalent (Performance Variant): EE2-4.5NUH-L from KEMET meets all critical electrical parameters with one operational difference: operate time is 2 ms and release time is 1 ms (faster than the 4 ms specification of the main part). Switching voltage and coil specifications are identical. Moisture Sensitivity Level is superior (MSL 1 versus MSL 3).

Engineering Selection Recommendations

V23079D2011B301 is a direct parametric equivalent suitable for applications where Cut Tape packaging is preferred over Tape & Reel. This part maintains identical electrical specifications and operating characteristics. ROHS3 Compliant status provides enhanced regulatory alignment for applications requiring the latest RoHS standards.

TX2SS-4.5V is a cross-manufacturer equivalent from Panasonic Electric Works suitable for applications requiring fully sealed relay construction. The sealed design provides enhanced environmental protection. Switching voltage specification is limited to 220VDC maximum (versus 250VAC capability of the main part). Tube packaging format accommodates manual assembly workflows.

EE2-4.5NUH-L is a performance-enhanced equivalent from KEMET suitable for applications requiring faster switching response. Operate time of 2 ms and release time of 1 ms provide improved response characteristics compared to the 4 ms specification of the main part. Superior moisture sensitivity level (MSL 1) eliminates moisture sensitivity constraints during storage and handling.

Selection between these substitutes depends on specific application requirements: packaging format preference, environmental sealing requirements, switching speed requirements, and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can V23079D2011B301 be used as a direct replacement for V23079G2011B301?

A: Yes. V23079D2011B301 is a parametric equivalent with identical electrical and mechanical specifications. The only differences are packaging format (Cut Tape versus Tape & Reel) and RoHS certification level (ROHS3 Compliant versus RoHS Compliant). Selection depends on assembly process requirements and regulatory compliance specifications.

Q: What are the key differences between TX2SS-4.5V and the main part?

A: TX2SS-4.5V maintains identical coil voltage, contact form, contact rating, coil current, and coil resistance. The primary differences are: switching voltage is limited to 220VDC maximum (the main part supports 250VAC and 220VDC), the relay features fully sealed construction, and packaging is Tube format instead of Tape & Reel.

Q: Is EE2-4.5NUH-L faster than V23079G2011B301?

A: Yes. EE2-4.5NUH-L operates with 2 ms operate time and 1 ms release time, compared to 4 ms for both parameters on V23079G2011B301. All other electrical specifications remain identical. This faster response is suitable for applications requiring reduced switching latency.

Q: Which substitute part has the best moisture handling characteristics?

A: EE2-4.5NUH-L has Moisture Sensitivity Level 1 (Unlimited), eliminating moisture sensitivity constraints. V23079G2011B301 and V23079D2011B301 both have MSL 3 (168 Hours). TX2SS-4.5V moisture sensitivity level is not specified but features fully sealed construction.

Q: Are all substitute parts RoHS compliant?

A: Yes. V23079G2011B301 is RoHS Compliant. V23079D2011B301 and EE2-4.5NUH-L are ROHS3 Compliant. TX2SS-4.5V is RoHS Compliant. All parts meet RoHS requirements.

Q: What packaging formats are available?

A: V23079G2011B301 is supplied in Tape & Reel (TR). V23079D2011B301 is supplied in Cut Tape (CT). TX2SS-4.5V is supplied in Tube. EE2-4.5NUH-L is supplied in Tape & Reel (TR). Selection depends on assembly equipment compatibility and production volume requirements.
