Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP2A-6R8-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value of 6.8 µH with ±20% tolerance
• Unshielded configuration
• Surface mount wirewound construction
• DC resistance within acceptable range (130–140 mOhm)

Secondary Compatibility Factors:

• Current rating capability at or above 1.2 A continuous
• Operating temperature range supporting -40°C minimum
• RoHS compliance status
• MSL rating of 1 (Unlimited)

The P0770.682NLT from Pulse Electronics satisfies these substitution criteria. Both components share identical inductance specifications (6.8 µH ±20%), unshielded wirewound construction, and surface mount packaging. The P0770.682NLT operates across -40°C to 130°C, exceeding the MP2A-6R8-R temperature range. DC resistance values (136 mOhm vs. 130 mOhm Max) remain within acceptable engineering tolerance. Current rating differences (1.49 A vs. 1.2 A) require application-level verification to ensure the substitute meets circuit load requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MP2A-6R8-R): Select the MP2A-6R8-R when the application requires the specified 1.49 A continuous current rating and operates within the -40°C to 85°C temperature envelope. This component is Active status with established supply availability (987 units in stock). RoHS Compliant certification and MSL 1 rating support standard manufacturing and storage protocols.

Substitute Selection (P0770.682NLT): The P0770.682NLT from Pulse Electronics serves as a functional equivalent when circuit current requirements do not exceed 1.2 A continuous operation. This substitute provides extended operating temperature capability (-40°C to 130°C) and maintains ROHS3 compliance. DC resistance characteristics (130 mOhm Max) remain within acceptable engineering tolerance relative to the primary part. Inventory availability is higher (2966 units in stock), supporting supply chain flexibility.

Selection Constraints:

• Do not substitute the P0770.682NLT in applications requiring continuous current above 1.2 A
• Verify saturation current requirements; the substitute is rated at 1.2 A Isat versus 1.53 A for the primary part
• Confirm physical package dimensions are compatible with PCB layout; the P0770.682NLT measures 0.260" L x 0.175" W versus 0.295" L x 0.205" W for the MP2A-6R8-R

Frequently Asked Questions (FAQ)

Q: Can the P0770.682NLT replace the MP2A-6R8-R in all applications?

A: No. The P0770.682NLT is suitable only for applications where continuous current does not exceed 1.2 A. If the circuit requires the full 1.49 A rating of the MP2A-6R8-R, the substitute will not meet performance specifications.

Q: What is the significance of the DC resistance difference (136 mOhm vs. 130 mOhm)?

A: The 6 mOhm difference represents approximately 4.4% variation. In low-impedance circuits, this may introduce measurable power dissipation changes. Calculate circuit-specific impact using I²R losses at operating current levels.

Q: Are the physical dimensions compatible between these parts?

A: No. The MP2A-6R8-R measures 0.295" L x 0.205" W (7.50mm x 5.20mm) with 0.071" height, while the P0770.682NLT measures 0.260" L x 0.175" W (6.60mm x 4.45mm) with 0.115" height. PCB footprint and clearance requirements must be verified before substitution.

Q: Do both parts meet RoHS requirements?

A: Yes. The MP2A-6R8-R is RoHS Compliant, and the P0770.682NLT is ROHS3 Compliant. Both satisfy current environmental and material restriction standards.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These components do not require special dry-pack storage or baking procedures prior to assembly, simplifying supply chain handling.

Q: Which part should I select for new designs?

A: For new designs, evaluate circuit current requirements first. If continuous current is 1.2 A or below, the P0770.682NLT offers extended temperature range (-40°C to 130°C) and higher inventory availability. If current exceeds 1.2 A, the MP2A-6R8-R is the only suitable option.
