BZV55C11-TP Equivalent & Substitute Parts

Part Overview

The BZV55C11-TP is a Zener diode rated at 11 V nominal with 500 mW power dissipation, manufactured by Micro Commercial Co in a Surface Mount Mini MELF package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 150°C and meets ROHS3 compliance requirements.

Substitute parts are identified based on matching electrical specifications (Zener voltage, power rating, tolerance, impedance) and mechanical compatibility (Surface Mount Mini MELF packaging). Active alternatives ensure supply chain continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitution eligibility for the BZV55C11-TP is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Zener voltage (Nom): 11 V
Power rating: 500 mW
Tolerance: ±5%
Impedance (Max): 20 Ohms
Reverse leakage current: 100 nA

Mechanical Equivalence Criteria:

Mounting type: Surface Mount
Package designation: DO-213AC, MINI-MELF, SOD-80

Compliance Criteria:

RoHS3 compliance
REACH unaffected status

All identified substitute parts meet these criteria. Differences in forward voltage characteristics and extended operating temperature ranges represent enhancements over the original part specification and do not preclude substitution.

Engineering Selection Recommendations

Upgrade Substitutes (Recommended for New Designs):

BZV55-C11,115 (Nexperia USA Inc.) and BZV55-C11,135 (NXP USA Inc.) are active products with extended operating temperature ranges (-65°C to 200°C versus -55°C to 150°C) and improved forward voltage characteristics. Both maintain full electrical and mechanical equivalence to the BZV55C11-TP while offering superior long-term supply availability. These parts are suitable for direct replacement in existing applications and preferred for new production.

Similar Substitute (Alternative):

BZV55C11 (Taiwan Semiconductor Corporation) is an active product meeting all core electrical and mechanical specifications. Operating temperature range extends to -65°C to 175°C. This part provides an alternative source for applications where Nexperia or NXP supply is constrained.

Compliance Status:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original BZV55C11-TP specification.

Frequently Asked Questions (FAQ)

Q: Can BZV55-C11,115 or BZV55-C11,135 be used as direct replacements for BZV55C11-TP?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical Zener voltage (11 V), power rating (500 mW), tolerance (±5%), impedance (20 Ohms), and package designation (DO-213AC, MINI-MELF, SOD-80). Extended operating temperature ranges and improved forward voltage characteristics do not affect substitution compatibility.

Q: What is the difference between BZV55-C11,115 and BZV55-C11,135?

A: Both parts are manufactured to the same electrical specification. The primary difference is packaging: BZV55-C11,115 is supplied in Tape & Reel format, while BZV55-C11,135 is supplied in Bulk. Electrical performance and mechanical compatibility are identical.

Q: Is the BZV55C11 from Taiwan Semiconductor Corporation a suitable substitute?

A: Yes. This part meets all electrical and mechanical equivalence criteria. It is an active product with ROHS3 compliance and REACH unaffected status. Forward voltage characteristics differ slightly (1 V @ 10 mA versus 900 mV @ 10 mA for Nexperia/NXP parts), but this does not preclude substitution.

Q: Why is the BZV55C11-TP classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Micro Commercial Co. Active equivalent alternatives from Nexperia, NXP, and Taiwan Semiconductor Corporation ensure continued availability for replacement and new production applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification and REACH unaffected status, matching the regulatory requirements of the original BZV55C11-TP.

Q: Can substitute parts be used in temperature-critical applications?

A: Substitute parts from Nexperia and NXP extend the operating temperature range to -65°C to 200°C, providing enhanced performance in temperature-critical applications compared to the original -55°C to 150°C specification. The Taiwan Semiconductor Corporation alternative operates to -65°C to 175°C.
