• Inductance tolerance: ±20%
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Core material: Ferrite
• Physical footprint compatibility: 7.30mm x 7.30mm nominal dimensions

Performance Parameters (Allowable Variation):

• Current rating: Minimum 600 mA (higher ratings acceptable)
• DC resistance: Maximum 610mOhm (lower values acceptable)
• Operating temperature range: Minimum -40°C ~ 100°C (extended ranges acceptable)

Compliance Parameters:

• RoHS status: Compliance preferred for new designs

Engineering Selection Recommendations

CDRH74NP-101MC-B (Direct Equivalent - Recommended Primary Substitute)

The CDRH74NP-101MC-B is the direct equivalent substitute for the obsolete CDRH74-101MC. Both components are manufactured by Sumida America Components Inc. and share identical electrical specifications: 100 µH inductance, 600 mA current rating, 610mOhm maximum DC resistance, and ferrite core construction. Physical dimensions and height are identical (7.30mm x 7.30mm x 4.50mm). The primary distinction is product status and packaging: CDRH74NP-101MC-B is active production status with Tape & Reel packaging and ROHS3 compliance, whereas the main part is obsolete. This substitute provides direct form, fit, and function compatibility with superior supply chain availability (220,400 pieces in stock versus 1,102 pieces for the main part).

DR74-101-R (Functional Alternative - Secondary Option)

The DR74-101-R manufactured by Eaton Electronics Division is a functional alternative meeting core electrical requirements with performance enhancements. Electrical specifications align: 100 µH inductance, ±20% tolerance, ferrite core, shielded configuration, and surface mount mounting. Performance advantages include higher current rating (860 mA versus 600 mA), lower DC resistance (383mOhm versus 610mOhm maximum), and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 100°C). Physical dimensions show minor variation (7.60mm x 7.60mm versus 7.30mm x 7.30mm), requiring PCB layout verification. ROHS3 compliance and active product status support long-term availability. This option is suitable when improved thermal performance or higher current margin is required.

P1167.104NLT (Functional Alternative - Tertiary Option)

The P1167.104NLT manufactured by Pulse Electronics is a functional alternative meeting core electrical requirements. Electrical specifications align: 100 µH inductance, ±20% tolerance, shielded configuration, and surface mount mounting. Performance characteristics include 630 mA current rating, 390mOhm maximum DC resistance, and extended operating temperature range (-40°C ~ 130°C). Physical dimensions show minor variation (7.54mm x 7.54mm versus 7.30mm x 7.30mm), requiring PCB layout verification. ROHS3 compliance and active product status support long-term availability. This option provides balanced performance between the main part and DR74-101-R alternative.

Compliance Considerations

All substitute parts maintain ECCN EAR99 and HTSUS 8504.50.4000 classifications consistent with the main part. Moisture sensitivity level remains MSL 1 (Unlimited) across all options. ROHS3 compliance is achieved with CDRH74NP-101MC-B, DR74-101-R, and P1167.104NLT, supporting modern design requirements and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-101MC-B be used as a direct replacement for CDRH74-101MC?

A: Yes. CDRH74NP-101MC-B is the direct equivalent substitute. Both components share identical inductance (100 µH), current rating (600 mA), DC resistance (610mOhm maximum), core material (ferrite), shielding, and physical dimensions (7.30mm x 7.30mm x 4.50mm). The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). Form, fit, and function compatibility is complete.

Q: What are the key differences between the substitute parts?

A: CDRH74NP-101MC-B is the direct equivalent with identical electrical and physical specifications. DR74-101-R and P1167.104NLT are functional alternatives with improved performance characteristics: higher current ratings (860 mA and 630 mA respectively versus 600 mA), lower DC resistance (383mOhm and 390mOhm respectively versus 610mOhm), and extended operating temperature ranges. Physical dimensions vary slightly (7.60mm and 7.54mm versus 7.30mm), requiring PCB layout verification.

Q: Are there physical footprint compatibility concerns with DR74-101-R and P1167.104NLT?

A: Minor physical dimension variations exist. DR74-101-R measures 7.60mm x 7.60mm (versus 7.30mm x 7.30mm for the main part), and P1167.104NLT measures 7.54mm x 7.54mm. Height dimensions are comparable (4.35mm and 4.50mm respectively versus 4.50mm). PCB layout verification is required to confirm clearance and placement compatibility before design implementation.

Q: Do all substitute parts meet RoHS compliance requirements?

A: CDRH74NP-101MC-B, DR74-101-R, and P1167.104NLT are all ROHS3 compliant. The original CDRH74-101MC is RoHS non-compliant. For new designs or applications requiring RoHS compliance, any of the three substitute parts are suitable.

Q: What is the inductance test frequency for each part?

A: CDRH74-101MC and CDRH74NP-101MC-B use 1 kHz test frequency. DR74-101-R and P1167.104NLT use 100 kHz test frequency. This difference reflects measurement methodology and does not affect functional performance at typical operating frequencies.

Q: Which substitute part offers the best thermal performance?

A: P1167.104NLT provides the highest operating temperature range (-40°C ~ 130°C), followed by DR74-101-R (-40°C ~ 125°C). Both exceed the main part specification (-40°C ~ 100°C). For applications requiring extended temperature operation, P1167.104NLT is the optimal selection.

Q: What is the current saturation rating for each part?

A: CDRH74-101MC and CDRH74NP-101MC-B do not specify saturation current. DR74-101-R specifies 990mA saturation current. P1167.104NLT specifies 630mA saturation current (equal to rated current). For applications requiring saturation current specification, DR74-101-R provides the highest margin.

Q: Are all parts available in Tape & Reel packaging?

A: CDRH74-101MC is supplied in nonstandard packaging with 1,102 pieces in stock. CDRH74NP-101MC-B, DR74-101-R, and P1167.104NLT are all supplied in Tape & Reel (TR) packaging with significantly higher inventory availability (220,400, 2,452, and 9,657 pieces respectively).

Q: What is the self-resonant frequency specification?

A: CDRH74-101MC, CDRH74NP-101MC-B, and DR74-101-R do not specify self-resonant frequency. P1167.104NLT specifies 6.2MHz self-resonant frequency. For applications requiring self-resonant frequency specification, P1167.104NLT is the only option providing this parameter.
