Engineering Selection Recommendations

Primary Selection: 151KD10 (YAGEO)

The 151KD10 is the original specified component with Active product status and established supply availability (926 units in stock). This part is suitable for new designs and ongoing production where YAGEO sourcing is established.

Substitute Selection: MOV-10D151K (Bourns Inc.)

The MOV-10D151K is a parametric equivalent offering identical electrical and mechanical specifications. This substitute is appropriate for:

• Supply chain continuity when 151KD10 availability is constrained
• Design flexibility requiring dual-source qualification
• Applications where Bourns Inc. supply chain is preferred

The MOV-10D151K carries RoHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. Inventory availability is higher (2939 units in stock), supporting extended production runs.

Both parts share identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications, ensuring consistent export and import compliance.

Frequently Asked Questions (FAQ)

Q: Can MOV-10D151K replace 151KD10 in existing circuit designs?

A: Yes. The MOV-10D151K is a parametric equivalent with identical varistor voltage (150 V nominal), surge current (2.5 kA), energy absorption (22 J), and package configuration (10mm disc through-hole). All electrical and mechanical specifications match exactly.

Q: Are there differences in product compliance between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications. The MOV-10D151K carries additional RoHS3 compliance and REACH Unaffected status documentation. Compliance requirements should be verified against specific application and regional regulations.

Q: What is the operating temperature range for both parts?

A: Both the 151KD10 and MOV-10D151K operate across −40°C to +105°C (TA). This range is identical for both substitutes.

Q: Are the package dimensions identical?

A: Yes. Both parts use a 10mm disc through-hole package configuration with identical mounting characteristics. PCB layout and mechanical integration are directly compatible.

Q: What is the moisture sensitivity level for these varistors?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.

Q: Can these parts be used interchangeably in high-surge applications?

A: Yes. Both parts are rated for 2.5 kA surge current and 22 J energy absorption. They are suitable for identical transient voltage suppression applications within these specifications.

Q: What is the capacitance specification at operating frequency?

A: Both parts measure 670 pF at 1 kHz. This capacitance value is identical and should be considered in high-frequency circuit analysis.
